Izixazululo

Ukubumba iplatinum kwenziwa kusetshenziswa inqubo enezinyathelo eziningi ehilela imishini ekhethekile kanye nolwazi olubanzi lokuthi izinsimbi eziyigugu, njengeplatinum, zincibilika kanjani. Inqubo yokubumba iplatinum ihilela izinyathelo ezilandelayo: Imodeli ye-wax kanye nokulungiselela ukubumba.

Ukulingisa Ubucwebe Beplatinum

Izitolo zobucwebe kanye nabanye abaklami bobucwebe bafuna ukukwazi ukuguqula ngokushesha imiklamo yabo ibe yizinto ezibonakalayo ezingathengiswa. Izinkampani zokulingisa iplatinum, njengeCasting House, zingasiza la mabhizinisi kanye nabaklami ukuthi bakhe izingcezu ngazinye noma ukukhiqizwa okukhulu ngokunikeza ukufinyelela kumasevisi okulingisa amahle kakhulu.

Ukuqonda Inqubo Yokuphonsa Iplatinum

Ukubumba i-platinum kwenziwa kusetshenziswa inqubo enezinyathelo eziningi ehilela imishini ekhethekile kanye nolwazi olubanzi lokuthi izinsimbi eziyigugu, njenge-platinum, zincibilika kanjani.

Inqubo yokubumba iplatinum ifaka phakathi lezi zinyathelo ezilandelayo:

Inqubo yokubumba ubucwebe beplatinum ifana nokubumba ubucwebe begolide nesiliva. Umehluko omkhulu kuphela ukuthi izinga lokushisa lokuncibilika kweplatinum liphakeme kakhulu elidingekayo elingaba ngu-1800 degrees celsius, lokhu kudinga ukwenziwa yiHasung Tilting Vacuum Pressure Casting Machine.

Imodeli ye-wax kanye nokulungiswa kokubumba. Ucezu lobucwebe beplatinum luqala ngokwakhiwa kwemodeli ye-wax yokuthi ucezu oluqediwe luzobukeka kanjani. Le modeli inamathiselwe esiqwini se-wax nge-sprue ezokwakha umzila lapho iplatinum encibilikisiwe igcwalisa khona esikhumbeni. Ngezinye izikhathi amamodeli amaningi e-wax azonamathiselwa esiqwini esifanayo ukuze kwenziwe ukubumba okuningi.
Ukutshalwa kwezimali. Uma imodeli ye-wax isibekwe esiqwini, ifakwa ebhodleleni bese kuthululwa izinto zokutshala imali nxazonke. Ngemva kokusetha izinto zokutshala imali, iba yisikhunta lapho i-platinum ewuketshezi izothululwa khona. Ukusetshenziswa kwezinto zokutshala imali ezifanele ekubunjweni kwe-platinum kubaluleke kakhulu ngenxa yokushisa okuphezulu lapho i-platinum incibilikisa khona. Nokho, ngaphambi kokuba i-platinum ithululwe esikhumbeni, imodeli ye-wax yokuqala idinga ukushiswa ehhavini elikhethekile. Lapho yonke i-wax incibilikiswa futhi ishiswa, ishiya imbobo ezintweni zokutshala imali ezisebenza njengesikhunta.
Ukuncibilikisa. Kunezinhlobo eziningana ze-alloy ezivamile ezivame ukusetshenziswa ekubunjweni kwe-platinum. Ezivame kakhulu yi-Platinum 900 Iridium, encibilikisa kuma-degree Fahrenheit angu-3,250; i-Platinum 950 Iridium, encibilikisa kuma-degree Fahrenheit angu-3,236; i-Platinum 950 Ruthenium, encibilikisa kuma-degree Fahrenheit angu-3,245; kanye ne-Platinum 950 Cobalt, encibilikisa kuma-degree Fahrenheit angu-3,182. Uma i-alloy isincibilikisiwe, ingathululwa esikhumbeni noma iphoqelelwe ukusebenzisa enye yezindlela eziningana.
Ukuphotha. Nakuba insimbi ewuketshezi ingathululwa nje esikhumbeni, amasu ahlukene ahlinzeka ngokuphotha kwekhwalithi ephezulu ngokulawula ukugeleza kwensimbi esikhumbeni. Ukuphotha kwe-centrifugal kusebenzisa i-centrifuge ukujikisa iflaski futhi kusebenzise amandla e-centrifugal ukusabalalisa insimbi ngokulinganayo kuyo yonke isikhumbeni. Ukuphotha okusizwa yi-vacuum kudonsela insimbi esikhumbeni ngokusebenzisa ukumunca. Ukuphotha kwengcindezi kubeka iflaski ngaphakathi kwegumbi elinomfutho. I-Casting House isebenzisa zonke lezi zindlela ezintathu kanye nokuphotha kwethoshi, okusebenzisa ithoshi ukuncibilikisa inani elincane kakhulu lensimbi elithululwa esikhumbeni.
Ukuhlanzwa Lokhu kuhilela ukususa ukuthungwa ekutshalweni kwemali, kungaba ngezindlela zomzimba noma zamakhemikhali. Ukutshalwa kwemali kungashaywa ngesando, kuqhunyiswe ngejethi yamanzi noma kudlidlizwe, noma abakhiqizi bangasebenzisa isisombululo ukuze bakuncibilikise. I-sprue ecezwini ngalinye iyanqunywa futhi isetshenziswe kabusha ukuze kuthungwe esikhathini esizayo, bese ingxenye eqediwe ihlanzwa ukuze kususwe noma yikuphi ukungapheleli.
Isidingo sokuhlanganiswa kolwazi olukhethekile kanye nokufinyelela emishinini ethile kusho ukuthi izitolo eziningi zobucwebe kanye nabaklami bathembele ezinkampanini zokuthunga i-platinum ukuze benze le nsizakalo. Ochwepheshe abasebenza kulezi zinkampani zokuthunga i-platinum banolwazi oludingekayo lokudala izingcezu zobucwebe ezisezingeni eliphezulu. Banokufinyelela nobuchwepheshe obusezingeni eliphezulu bokubumba kanye ne-photopolymer.
